Ice has a bad taste or odor (plastic, chemical, or musty).

Safety first: Unplug the unit before cleaning. Do not use harsh chemicals that are not food-safe.

• Discard old ice: Empty the ice basket and discard any ice with off-odors.
• Deep clean: Drain the reservoir. Clean the reservoir, ice tray, and bin with a mixture of warm water and mild dish soap, followed by a rinse with a vinegar solution (1:1 water and white vinegar). Rinse thoroughly with clean water.
• Clean water lines: Run a cleaning cycle with vinegar solution if your Igloo model supports it, then flush with at least two full reservoirs of fresh water, discarding the ice.
• Use better water: Switch to filtered or bottled water to reduce chlorine and mineral tastes.
• Odor control: When not in use, empty the unit, dry the interior, and leave the lid slightly open to prevent musty odors.
